This invention relates to removable closures for receptacles andparticularly to sheet metal barrels or drums used as shipping or storagecontainers. When such receptacles removable closures be provided withlocking means for securely locking vsaid closures in closed position sothat accidental displacement thereof can not occur in the handling andtransportation of the receptacle, while for storage it is desirable toprovide locking means which, whilemaintaining the closure in securelylocked position, may be readily manipulated to permit the closure to beeasily removed at will. A

The principal object of the ypresent invention is to provide a' newandimproved construction of a receptacle closure including a pluralityof locking means adapted to be 'interchangeably used to fulfill theabove requirements. A further object is to so construct the closure andthe locking means therefor that danger of leakage about the points ofconnection of the locking means to the closure is prevented.Otherfobjects will appear more fully from the following more detaileddescription and' by reference to the accompanying drawings, showingvarious illustrative examples of my invention. In said drawings, Fig. 1is a. fra menvertical section of a receptacle c osure ta anldlra lockingring therefor; Figr 2 is a fragmentary plan view of the cover shown inFig. .1 showing a different construction of the closure seating members'and illustrating the manner in which a pivoted locking means may be Yinterchangeably used, Fig. 3 is a view similar to Fig. 1 showing-anapplication of my invention to a ldifferent form of cover seatingringhand Fig. 4 is a view similar to Fig. 1A

showing a slightly modified form of the pivoted locking means.

As shown in Fig.` l,the receptacle A has its side wall portion bent toform a'lap joint 11 with a sheet metal supporting ring 12, s'aidringforming a support for a cover seating ring 13. The latter, in theexample shown, is channel-shaped in cross section, the lower flange 14of the channel, in the illustrated example, extending inwardly beyondthe upper flange 15 thereof. The inner edge of the supportingy ring 12is bent backwardly about the inner edge of the'lower flange 14, saidsupporting ring 12 cooperating with the horizontal flange 16 of an outerreinforcing ring 17 to hold the cover seating ring 13 securely inposition.'

' The cover 18 is preferably constructed ol' two sheets 19 and 20 spacedfrom'each other to form a chamber 19a and connected together adjacent totheir outer edges by any suitable means such as a lap joint, the outerperiphery of the cover being formed to provide a horizontally extendingmarginal flange 21, the arrangement being such that at least one of saidsheets is shaped to forni an annular flange 22 depending from the inneredge of' the marginal flange 2l. ll desired, a protective annular flange.23 may surround and project below the flange 22, said flange 23 in suchcase being fastened in place by the aforesaid lap joint. When the PATENTy OFFICE.

fil

cover is in position on the, receptacle. the

vertically extending flange 25 of a locking ring 26 is adapted to beengaged. The locking ring 26 isof angular cross section and has a.horizontal flange 26a which is adapted to be inserted under the upperflange 15 of the cover seating ring and serves tohold the marginalflange 21 ofi the cover pressed tightly against a packing 27 which restsup' on the lower flange -14 of .the vcover seatingl ring 13. The lockingring26 is split at any suitable point of its circumference and isadapted to be forced into locked position, to hold the cover lsecurelyin position. lVhen the Alocking ring'is sprung into locked position,acc1dental displacement thereof is practically impossible, as it isnecessary to use' :1 suitable tool to jimmy the ring out' of said lockedposition. Therefore it is desirable, when the receptacle is used-forstoring materials`to which access isdesired at frequent f lat rightangles to the position shown in Fig. 2, to engage under the upper flange15 of the the closure, for. instance by stamping out the sheet -19 atthe proper points, to arrest the- .swinging movements of said latches 28to# ward inoperative positions. y

In Fig. 3, the coverseating ring 13a 1s` constructed of sheet metal andis thus slightly dierent from that ofthe ring 13 Shown in Fi 1. *Theouter ed e of the cover seat? ing ring 13a ,is connecte Iby a lap joint11a with the side wall of the receptacle 10a. The .ring 13a is providedwith ana-upwardly rojeeting bead 33 which cooperates with t e horizontalllange 16a. of the outer reinforcing ring l' to 'form a channel in wh1chthe,

ends of the4 latches 28 may be engaged .or

. in which the horizontal llange 26?x of 4the 29 by means of which thelatches 28 are se# lookin ring may be inserted. The constructiono thecover shown in Fig. 3 is identical with that shown in Fig. 1. l While itis preferable to extend the'rivets cured. to the cover, only throughIthe upper v sheet 19, so that if the rivet should become which projectthrll loosened leakage is prevented, it will be understood that incertain eases it may -.be desirable to extend the rivetsthrough both ofthe sheets 19 and 20 of the cover.

In Fig. 4, I have shown a construction in which the latches '28 arellocated on the interior face of the cover so that when the latch isswung to locking position, it will engage. under the lower Ilan e 14ofthe cover seating ring in Fig. 1 or its equivalent in Fig. 3;" it willbe l'lnderstood that in such case thelatches 28ffiare fixed upon stems29 both sheets, 19 `and 20 of the closure and yond the upper sheet 19;the projecting ends are rovided with handles 30 accessible fromt eexterior of 'the closure for manipulating said latches.

In all lof the forms of my=invention, thev latches when in operativepositions, securel' lock the closure or cover 1n lts closedposi- `tion,saidlatches being easily adjustable to. inoperative positions. in' which'the' closure or coverisreleasedand -thus capable of being readilyremoved at will to expose theinterior of the receptacles. It will beunderstood that such latches when in their inoperative` positions do notinterfere with the useof the locking ring.

It will be understood that various changes and modifications in thespecific forms shown` and described may be made `within the scope 4of4thel claims without departing from the spirit. of my invention.

I claim: L

1. In a receptacle closure, a cover -comprising an inner sheet andl anouter sheet secured together .adjacent to their marginal edges with theintermediateportions of said sheets in spaced relationship from each'other, a plurality of locking latches ,and

0* said latches to said outer means for securln sheet only, wherebyleakage about -said se- Y curing means isprevented lby said inner sheet.

v2. The combination with a reeeptacleihav-Y 'ing an open end, and a pairof horizontally extending flanges lspaced one above the other at saidopen end, the lower of said flanges extending inwardly of the upperflange to form a support for a cover, of a cover having a horizon-tallyextending pe-A ripheral flange adapted to be supported by said lowerflange and thereto a lurality of latches 'for temporarily securmg it 1nclosed position, said latches being freely movable upon their pivotsinto and out of locked engagement with the under side of said upperflange, -a split locking ring engageable with said upper I lange andsaid cover and movable into-'and out of locked engagement therewith.only bythe use 'of a leverage exertin tool, said pivoted latches whenswung to fu l unlocked position providing suilicient clearance `space topermit the engagement of said split locking ring with said upper flangeand cover, whereby'either said pivoted latches or said v split lockingring respectively may be inter to close said open- .end, said coverhavingpivotally secured and upper flange for temporarilylocking v saidcover in closed position for storage purposes or frmore permanentlylocking itin closed position for shipping purposes.

In testimony whereof I have hereunto set my hand. i v L' ALFoNs MAUSER.i
